Abstract: A rescue signal device for use in rescue or retrieval operations is disclosed. The rescue signal device is a polyhedral object including multiple reflective surfaces. The rescue signal device is generally spherical or hemispherical, with the multiple reflective surfaces providing it with numerous facets off of which light is reflected. Usually, the reflective surfaces will be mirrors. The rescue signal device may be buoyant enough to float on water, or if inflatable and a lighter than air gas is used, sufficiently buoyant to float in the air. The rescue signal device may be provided with a frame to increase its stability, and may be mounted on a pole or other support. If mounted upon an object, it is generally able to rotate such that it creates scintillating reflections as it moves. The rescue signal device may also include wind cups to encourage its rotation in the wind.
